PTA cladding

PTA cladding

PTA cladding is a coating method to apply a wear-resistant and/or corrosion-resistant material to a part. PTA is an abbreviation for Plasma Transferred Arc. This name is derived from how the material is transported by plasma. The powdered material is added to the welding arc, allowing it to melt. The compound created by PTA cladding is metallurgical. With a PTA source, the surface of the cladded part is melted. At the same time, a metal powder is applied to the molten workpiece surface. This powder melts and bonds with the base material.


Advantages of PTA cladding

Significant advantages of PTA Cladding compared to conventional welding processes such as TIG and MIG welding is the minimal heat input and, therefore, low mixing with the base material. An additional advantage of this technique is the limited deformation of the base material. An alternative to PTA cladding with an even lower heat input is laser cladding. We are happy to advise you on the best choice for your project.













When is PTA cladding used?

PTA cladding can be applied to many different parts. The protective layer that is applied ensures better tool life and reliable performance. Depending on the application, other materials can be used. PTA cladding can be used, for:

  • Valves
  • Seats
  • Transport screws
  • Plungers
  • Valves
  • Pump parts
  • Drilling tools


Is PTA cladding the solution to your wear problems?

We are happy to help you reduce wear and tear on your machine parts. By means of PTA cladding, we ensure that your processes or products have a longer service life. This prevents unplanned repairs and high maintenance costs. Investing in a wear-resistant surface coating is therefore definitely worth it!
